The Doddger plan shows the CG at 2 3/8" from the leading edge of the wing. The plan I have does not specify the control surface throws.

To start with I would suggest 3/16 up and down (3/8 total) on the aileron and 1/4 up and down (1/2 total) on the elevators.

After a few flights you will very likely move the CG back and cut down on the throws. All of my Quicky racers have the CG at 3" from the LE. The throws are considerably less than above. Start with the throws I suggest. There is not much worse than an airplane with not enough control throw and you are trying to land it!!
